Synopsis
A weak weather disturbance will bring the threat of thunderstorms
to the northern mountains on Wednesday. Otherwise, the weather
will be dry and mild through the remained of the week. The weekend
will see continued dry weather but warmer temperatures. The a dry
cool front will bring breezy and milder weather to the region by
the 4th of july.

Discussion
Tonight through Thursday: the low that was partly responsible for
yesterday's weather is still up in bc alberta. The northerly flow
on the backside of this low will bring the chance of thunderstorms
to form over the northern mountains of washington and idaho. The
models are quite disparate on this situation. They also show
surface-based instability, but most don't show any precipitation
being generated. The ECMWF and SREF about the only models with
precipitation. I've decided to put a slight chance of thunder
storms for northeast wa, the pasayten wilderness, an the northern
panhandle. If any storms do develop, the northerly flow has the
potential to carry them off the mountains and in to the spokane
metro area. At this point i've left the mention of showers storms
out of the spokane cda forecast, but the night shift may need to
add it.

By Thursday, the offshore ridge will amplify which should push any
shower chances off to the east. This will also begin the start of
the next round of warming temperatures. Rj
Friday through Tuesday: the ridge that was in the area will begin
to flatten into a zonal flow pattern allowing a weak push of
moisture along the canadian border and will bring a chance of some
light precip and possible isolated lightning strike. After a
brief ridge, a trof will move into the region beginning late
Sunday. The model agreement of how deep the trof digs is pretty
low but is expected to be a drier trof with very little precip
chances. This is expected to bring breezy conditions to the
columbia basin as the gradient tightens across the region.

Sustained winds in the low teens and gusts into the mid 20s will
be expected. Temperatures will be near normal with highs in the
upper 70s to 80s and lows in the 50s. Jdc

Aviation
06z tafs: expect dry weather and mostly clear skies through
Wednesday morning. Then a mid level wave will track across ne
washington and N idaho Wednesday afternoon and evening with a
chance of showers and thunderstorms over the mountains. A few
model solutions suggest this activity may clip kgeg ksff but kcoe
stands the better chance. For now kept thunder out of all taf
sites given the better chances for storms over the mountains but
can not competely rule out a storm with gusty outflow winds at
kgeg ksff kcoe after 21z wed. Jw

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
